Betting slips 'epitaph' of Higgins under hammer
The scrawled notes were penned by the former champion the year before his death last July, a spokesman for Hansons Auctioneers said.
They were given to journalist David O'Dornan who spent two days with Higgins in 2008.
O'Dornan said: "It's a bizarre range of notes which provide a fascinating insight into the mind of the troubled genius that was Alex Higgins
"Most of them are on betting dockets, there is one on the racing page of a newspaper and another is on the back of a bar receipt."
One of the notes reads: "Was always honest and tried my best. Feeling good or feeling bad, tried my best."
Known for his fiery temperament and audacious skill with a cue, the Northern Irishman was credited with revolutionising the popularity of the sport. He died in July last year after battling throat cancer for almost a decade.
Hansons Auctioneers manager Charles Hanson said the notes were "almost like an epitaph".
The notes, which have been given a guide price of 1,000 to 1,500, are due to be sold by Hansons Auctioneers in Derby tomorrow.
